STAMPENG- ATTAClEM/IENT FOR HIDE. SPLITTERS.

appiicaiioa inea nuff er,

To all whom z'tmey concern/f v Be it known that it, lnwnrr F. lilniiinr, a citizen of. thellnited States, residing at Endicott, in the county of Broome and State oit-New York, have invented certain new and useful improvements in` Stamping; ittaclr ments for l-lide Splitters;` and l hereby declare thatv the followingis a full, clear, and

exact description thereof, reference being" had to the .accompanying drawings, which form part of this specification.

This invention is a novel mechanism for stampingl green hides, before placing same in the tanning liquors, in order to identify the particular kind of hide by the stamp; and also includes novel means for making `small incisions in the split halves of the hide to enable the two halves tobe readily tied together for subsequent treatment. d

lhe invention `is especially adapted for connection with the splitting horses on which the hides are usually `split preparatory to tanning; but may be used separately hereiuaon if desired.` e

ln the common method of stamping1 hides, after the green hide is thrown over the horse and before the hide is split, a die attached to the head ot a hammer-like instrunient is forcibly brought down upon the hide by successive strokes to impress the outline of the die in the surface of each half of the hide, the stamp being` usually made at the head end or butt end of the hide. After the stamping` thev operator splits the hide with a knife andthen customarily makes a small incision in each half of the hide with a short bladed knife, near the split therein to enable the` halvesof the hide to be tied together by a cord inserted through such :incisions whereby the halves of the hide are kept together during` the tanningl thereof.` e

My present `invention is particularly designed for use in connection with such hide splitting; horsesand enables both halves ofthe hide to be simultaneously stamped, and incisions to be simultaneously made in each half of the hide, to enable the halves to be tied together. i

ln the accompanying drawings lt have illustrated one practical embodiment of the invention as attached to an ordinary hidesplitting horse and will explain the saine with reference to said drawings; and `sinninarize in the claims the essentials of the Specification of Letters Patent.

lu said drawings: Figure l is a side view of part of a hide splitting` liorse7 showing my novel stamping` and incising devices applied thereto.

Figure 2 is a detail-top view of Figure l. Figure is an end view of Figure l. Figure 4 is an enlarged detail sectional view looking downward on line l-- ^i, Figure l.

Figure 5 `is an enlarged vertical sectional view.v on the line 5-,5, Figure l.

A., il, designate the paralleltop bars of a. hide-splitting horse arranged y horizontally and slightly separated and supported by legs B which may be connected at the bottomby tie-rod and may be fastened to the bars A, A and to each other l by bolts l) (sce Figures .1', 2 and 3). The particular construction of the horse is not a feature of the `present invention; it may be of any suitable construction.

Adjacentene end of each bar A is a stamping,1 member-l, which is preferably attached to the upper end of a vertically disposed shaft ieguided in a sleeve lI attached to the adjacent bar A. The stamp member l is provided on its under side with a socket for the reception of a removable stamp or die S which can be secured thereto by a holt la; the face of the die S projects below the lower sidey of the member i, but is held by said member above the tcp of the har A, when shaft l is in normal position as in Figures l* and 2. Preferably a lead block 1l) is inserted in a recess in the upper side of each bar A below and adjacent the related die S and serves as a platen for such die. The member l may be formed on or fastened to the upper end of shaft Fin any suitable manner. As shown :it is formed separat-ely and has an opening in one end fitted to the shaft and secured thereto in any suitable manner, preferably so that said member can be adjusted both vertically and also rotatably on` the shaft le, so as to insure proper positioning of the cutter 1S relative to the block 11.

Each shaft le, is preferably reduced in diameter below the sleeve lf, as at lg g and to the reduced portions lg are attached inembers or castings 2 (seelligure el) having arms 2", which are connected by a stout contractile helical spring 2E. The castings 2 have other arms 2", which project approximately at right angles to arms 27 and each arm 2b is connected by a link 2fto one arm of a bell crank lever 3, the other arm of which lever preferably carries roller 3 and engages the treadle lever hereinafter referred to.

Preferably each link 2t is pivotally connected to the head of a pin 2c engaging a vertical opening in the related arm 2"; and the other end of the link 2f is pivotally connected to a pin 3b in the end of the upper arm of the bell crank lever 3, these connections permitting relative oscillating and rocking movements of the arms and lever.

The lower end lg of each shaft le extends through an opening in a vertically movable bar d, and is suitably connected therewith so as to be moved thereby. Preferably a lball thrust bearing Ll is interposed between the upper side of the bar l and the casting 2; and a similar ball thrust bearing d 'is interposed between the underside of the bar 4f and a. collar lc on the lower end of part lg of the shaft below the bar, said collar being retained o n the shaft by a nut 1h, or other suitable means.

The bar l may be raised or lowered, to raise or lower the shafts le and stamp members l, by any suitable means. As shown an eye bolt 5 is attached centrally to the bar d, and to this eye bolt is pivotally connected the upper ends of links 5a which depend on opposite sides of an angular treadle lever. 6 and are pivotally connected to the knee of said lever as at 5b. The end of the short arm of this treadle lever is pivoted at 66L to suitable supporting bars 9 attached to the horse as shown. rllhe long arm 6b of the treadle lever extends upwardly and outwardly and has a fiat upper edge which is engaged by the roller 3 of the lever 3 (see Figure l).

The treadle lever G, bar Ll, shafts le, and stamp members l, are normally held in the position indicated. in Figure l, by means of suitable springs. lfeferably a rod 7 is pivotally connected to the pin 5l intermediate the links 5, said rod 7 may be threaded and adjustably secured to the pin by nuts 7, as

indicated in dotted lines in Figure l. On the outer end of rod 7 is hung a plate 7b to which are connected stout contractile springs 8, the outer ends of which are connected to a plate 8a attached to a convenient part of the frame or base as shown. Any other suitable arrangement of springs may be usedto hold the stamp carrying members l and the treadle normally in elevated position, as in Figure 1.

lin the construction shown when the lever G is depressed shafts le and stamps l are depressed so as to bring the stamps into contact with the hides overlying the blocks 1b; the springs 8 being more powerful than the spring 20; when the lever G is released its ends (Sb raises and` the roller il engaging (3" rocks lever 3 into the position shown in lull lines in Figure l, and through the connections cause the. shafts l to turn as they rise7 and cause the stamp members` l to swing laterally outwardly away from each other to the position (shown iu full lines in Figure 2). The stamps are thus moved from positions directly above the blocks l, and sufficient space is left between the members l, when the parts are in raised position to enable the workman to readily adjust the hide on the horse in the usual manner in position for stamping and cutting. lllhen the treadle is depressed and shafts le and members l lowered, the spring 2@ causes the shaft 1 to turn as they descend and the members l swing inwardly toward each other to the position shown in dotted lines in Figure 2 and bring the stamps directly over the blocks l" and impress the hide lxsely adjacent the slot n. between the bars The inturning movement of the stamping members enables the stamps to be applied very close to the edges of the halves ol the hide. l'. knife can then be inserted in slot 0;, between bars AA., and the hide .split into two parts as it rests on the horse. The hide can be split while the stamps are held engaged therewith and this assists in keeping the sulit or cut straight, so that the eut ed ges of the halves when tanned are straight instead of irregular.

Any other suitable means may be eniployed to cause the shafts or stamping members to turn toward each other or the renter line of the horse as they arc depressed, and to separate as they are elevated.

Preferably a cutter or knife (l is attarhed to the under side of eachv stamp bleek l between the stamp S and the shaft; and so positioned that when the dies are depressed to stamp the hides incisions about one and onehal f iuehes in length are made at the. .same time b v the cutters C in each .halll of llie hide adjacentl to the stamp. '.lhese incisions enable the two halves of the hide to be readily tied together and thus treated alike during the tanning process as is eustoniary. .In the process commonly used the tanner cuts slits in the hide with a short bladed knife after splitting it for tieing the halves logether and this has resulted in a lack of uniformity in the sizes of the slits, and increases the time and amount of work involved in preparing the hides. as com pared with the amount of work required when my invention is used.

il (l lOO By the addition of the cutter C thel numi ber of operations necessary to prepare the, hides for the vats is reduced, because, these incisions are an essential step in the process of preparing the hides for tanning, and by im ener my invention they are autotmatically made in each hide before it is placed in thevat.

Ubviously changes may be made in the particular construction of the parts while Operation;

A green hide is thrown over the horse and the head or butt portion of the hide is inserted under the members l and over the blocks 11. Then the operator depresses the treadle 6 with his foot thereby bringing the stamps forcibly down upon the hide and impressing the stamps thereon. At the same time the cutters C make small incisions or slits in the' halves of the hides to enable them to be tied together. After the impressions and incisions have been made, and preferably while the hide is clamped by the stamps, the hide may be slitted from head to tail by the operator drawing a sharp knife lengthwise between the two top bars of the horse.

Some of the advantages of my invention are: the stamps are made exactly in the same place on each half of `each hide; they are thoroughly legible; the work isuniform; the stamping is greatly facilitated; as the operator by simply depressing the treadle performs o erations that heretofore ordinarily require four operations by hand, to wit, picking up a hammenwith die inserted in the face, striking each side once with the hammer and then laying down the hammer. Additional advantages are the simultaneous making of the slits or incisions in the halves of the hide, at the same time the stamps are made with `no eXtra work on the part of the operator; the mechanism is simple and no special skill .is required by a workman to operate it; and the parts are automatically returned to original position by the ,springs when the treadle is released.
